Hi everyone =) I bought the escort 8500 x50 about two weeks ago and have been using it just about everyday. I have it on highway mode all the time, and it seems to detect about every walmart or convenient store. I've seen about 25 cops within these two weeks, but my detector hasn't went off once. At first I figured it was probably cause they didnt have any radar on, but could that be the case for ALL of them. Or does my radar not detect canadian cops lol.. On the otherhand I haven't ran into speed traps or highway patrol, but I still figured that maybe the cops in the city would occasionally have their radar on..
